What constitutes a kickass song?

I’ve got a playlist on my iPod called Kickass Songs. I’m listening to it right now. Right now what’s playing is “Guarded by Monkeys” by Cracker. And I just listened to “Cowboy” by Kid Rock, but I’m wondering what for you constitutes a kickass song? There are so many other ones that are on here — lets see, “Dirty Laundry,” “Hard to Handle,” “Honky Tonk Women,” “Sweet Emotion.” listen
